n z claims; (c1. 24a-276) i This invention relates in general to lightsignals for use on railways, and has more particular reference to animproved means for adjustably securing a signal casing to a signal pole.

The present application is a division of my application, Ser. No.470,056 filed July 23, 1930,

now Patent Number'2,097,785 dated November 2, 1937,Y for Light signalforrailroads.

Among the objects of myinvention is to provide an improved mountingmeans, which is simple in construction, relatively cheap to manulfacture, dependable in operation, and rugged and long lived.l

y Further objects, -purposes and characteristic features will appear asthe description progresses,

ing,Y showing, solely by way of example, and in no manner in a limitingsense, one vform which p the invention can assume. In the drawing:-

,The single figure kof drawing is a side elevational view, with partsshown in section, of one form which the invention can assume.

Referring now to the drawing, there is here shown a signal pole I, onwhich is carried a cap 2, adjustable horizontally thereon and then ilX-rable in adjusted position. The cap 2 has a transverse slot 21 formedtherein, with lugs 2z at the inner ends of the slot, to receive threadedbolts 3 and nuts 31 `for drawing a U-shaped strap 32, having an inwardlyprojecting pin 41, against the pole I, pin; 41 tting into a receivingsocket 42, in vpole I, to thereby anchor the strap to the pole, andadjustably connect the cap'y 2 to the anchored strap.

, With this arrangement of parts, cap 2 can be readily adjustedangularly'on pole I, by tightenking one of the nuts 31, and looseningthe other, f to thus turn the cap on the anchored strap.

Carried by the cap 2 is a signal casing SC, pivoted as at 4 to the cap2, and having an adjusting means, comprising a threaded stud 5 and nut Y6, for tilting the casing SC in a vertical plane l l vCarried within thesignal casing SC is a mechaf on its pivot point 4.

nism casing MC, having a depending bracket 1, earring a pin 8 at itslower end for engagement in an aperture 9 in a lug I0 carried by thesignal Y n casing; The signal casing has two pins II, in

. its sides, for cooperation with two latches I2,

pivoted at I3 to they mechanism casing, and biased by springs` I4 in acounterclockwise direction as viewed in the drawing, whereby to snap thelcatches I2 over the pins I I and thereby hold the mechanism casing MCin position in the 55 signal casing SC onthe two horizontal pins l I andthe lower 'pin 8.

adapter I8, having at its outer end a lens I9,

shown as a planoconvex lens of the condensing type, for directing lightbeams passing therethrough in a substantially cylindrical beam. Carriedon the adaptor I8 is a sunshade or visor 20, and carried by the signalcasing is a background 2| fastened in place by screws or the like 22.

In combination with the lens I9, is an auxiliary lens 23, carried in abracket 24 fastened to the adaptor I8.

The above rather specic description of one form of the presentinvention, is given solely by way of illustration, and is not intended,in any manner whatsoever, in a limiting sense. Obviously, the inventioncan assume many different physical forms, and is susceptible of numerousmodincations, and all such forms and modications, as come within theappended claims, are intended to be covered by this application.

Having described my invention, I now claim:-

1. In a light signal, in combination, with a signal casing and a signalpole, means for adjustably supporting the casing on the pole, in-

i cludlng, a cap fitting over the end of the pole means for anchoringthe strap to the pole, whereby to adjust the casing on the pole, in atransverse direction.

2. In a light signal, in combination, with a signal casing and a signalpole, means for adjustably supporting the casing on the pole, including,a cap fitting over the end of the pole, means for connecting the casingto the cap, a semi-circular transverse slot in the cap, a semicircularstrap in the slot and movable therein,

an ear at each end of the strap, an ear at each end of the slot, boltsfor each connecting a strap ear to a slot ear, a stud on the strapintermediate the ends thereof and projecting inwardly of the strap foranchoring the strap to the pole, whereby the bolts can rock the cap andits carried signal casing relatively to the anchored strap.
